Recently, increasing availability of natural gas, due to the shale gas, raises the attention to the conversion of methane. Methanol-to-Hydrocarbons reaction (MTH) plays an important role in this route where methanol synthesized through syngas is converted into hydrocarbons, such as Gasoline. In this study heat and mass transfer for MTH reaction over ZSM-5 as catalyst for an specific microreactor ...

The performance of a PEMFC depends on several factors, including the flow inside gas channels. Low gas velocity inside the channel can make water management more difficult, possibly causing water to accumulate and condense in certain regions of the cell. In the present work, COMSOL Multiphysics software was used to visualize and describe gas flow inside the channel of a PEMFC operating with ...
